Abstract

L'invention concerne un bioréacteur obtenu par compression d'un mélange d'une enzyme, d'un conducteur et de chitosane. Le conducteur peut être constitué de nanotubes de carbone. Ce bioréacteur peut être fabriqué selon les étapes suivantes : préparer un mélange de poudres dans laquelle la proportion de poudre d' enzyme par rapport à une poudre de nanotubes de carbone est de l'ordre de 50/50 en poids; préparer une solution visqueuse de chitosane dans un rapport de 5 à 15 (en mg) de chitosane à 0,75 à 1,25 (en ml) d'acide acétique dilué à 0,4 à 0,6 % en volume dans de l'eau; ajouter au mélange de poudres la chitosane visqueuse dans une proportion pondérale de 3 à 5 pour la poudre à 5 à 10 pour la chitosane; procéder à une première compression puis à un broyage léger; procéder à une deuxième compression pour réaliser une pastille; et sécher à température ambiante.
